Frameline, the world’s biggest, longest-running festival of queer cinema, presents the 46th time from Thursday through June 26 with in-person screenings at a record number of Bay Area venues and a national streaming encore June 24-30. A headliner among the more than 90 films from 30 countries is the panoramic, intimate documentary “Impresario,” which is about Frameline co-founder and legendary San Francisco filmmaker and showman Marc Huestis.
